The causeway, called Granite Island Road, is still a working structure between the mainland at Victor Harbour and Granite Island. The causeway was originally constructed of `colonial gum'.
The causeway is of pile driven construction, with each Bent having three piles at its original stage of construction. The geology of the area between the island and mainland is limestone over granite and it is into this the piles had to be driven.
The 630 metres (2,070 feet) long viaduct or pier, locally described as a causeway today daily accommodates foot traffic, horse drawn tram, light vehicles and occasional heavier traffic. A rail system for the tram runs the length of the causeway. The rail is broad-gauge. The conveyor belt strip running down the centre of the broad-gauge rail was placed to help the horses keep their footing when the timbers get wet. On the east side of the causeway there is a delineated strip for foot traffic.
Type: Plank Bridge
